What is the area of this triangle?
A=bh2
a-54 cm²
b-90 cm²
c-108 m²
d-216 m²
Answer:
a
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here b = 9 and h = 12 , then
A = [tex]\frac{1}{2}[/tex] × 9 × 12 = [tex]\frac{1}{2}[/tex] × 108 = 54 cm²

Machine A and machine B both make car parts.
Machine A makes 7 parts every 10 minutes.
Machine B makes 16 parts every 15 minutes.
On Monday
machine A makes parts for 12 hours
machine B makes parts for 10 hours
Work out the total number of parts made by the two machines on Monday.
Answer: 1144
Step-by-step explanation:
Given: Machine A makes 7 parts every 10 minutes.
i.e. it makes [tex]\dfrac{7}{10}[/tex] parts in 1 minute.
Machine B makes 16 parts every 15 minutes.
i.e. it makes [tex]\dfrac{16}{15}[/tex] parts in 1 minute.
On Monday,
machine A makes parts for 12 hours(720 minutes). [1 hour = 60 minutes, 12 hours = 12 x 6 = 720 minutes]
i.e. Total parts made = [tex]\dfrac{7}{10}\times720[/tex]
i.e. Total parts made = 504
machine B makes parts for 10 hours(=60x 10=600 minutes)
i.e. Total parts made = [tex]\dfrac{16}{15}\times600[/tex]
i.e. Total parts made = 640
Total parts made by both machines = 504+640 =1144
Hence, the total number of parts made by the two machines on Monday=1144.
A dolphin is at -25 feet. It swims up and jumps out of the water to a height of 10 feet. Write a subtraction expression for the vertical distance the dolphin travels
Answer:
35 feets
Step-by-step explanation:
Initial Position = - 25 feets
Final height reached after jumping = 10 feets
The vertical distance traveled by dolphin :
Final height reached - Initial position
(10 feets) - (-25 feets)
10 feets + 25 feets
= 35 feets

Deana made a scale drawing of her patio using a scale of 1/2 cm =1 foot what is the actual width, in feet, of deanas patio
Full question attached
Answer and explanation:
Given that 1/2cm= 1 foot
5cm= 2×5=10 feet
Length is twice the width, therefore real length of shape = 10×2=20 feet
Perimeter is sum of all sides= 20 feet+20 feet+10 feet+10 feet = 60 feet
Therefore Deana's Patio= 60 feet in real length

I'm really struggling with this problem can someone please give me an examples like this problem or explain how to solve it an problems like it.
Answer:
Step-by-step explanation:
Ok so I'm not 100% sure how to solve this but what I would do is use the equation a^2 + b^2 = c^2 this equation is used to solve for the hypotenuse or the longest side of a triangle. To find a^2 you would do (21+15)^2 (Also this symbol ^ is the power symbol) and the answer would be 1296. b^2 would be 25^2 or 625. The equation turns out to be 1296 + 625 = c^2. c^2 (or x in this case) would be 1921. To find just c and not c^2 you would find the square root of 1921 which is 43.8292140016 or if rounded would be 43.8. Also this might not help if I misinterpreted the question...

A bag contains 5 red marbles, 8 blue marbles and 4 green marbles. If three marbles are drawn out of the bag, what is the probability, to the nearest 10th of a percent, that all three marbles drawn will be red?
Without replacement, the probability that all three marbles drawn will be red is 0.01.
What is the probability?Probabiliy is used to determine the likelihood of an event happening. The probability that the event would occur lies between 0 and 1.
Probability of drawing three red marbles = (number of red marbles / total number of marbles) x (number of red marbles / total number of marbles - 1) x (number of red marbles / total number of marbles - 1)
5/17 x 4/16 x 3/15 = 0.01
The probability, to the nearest 10th of a percent, that all three marbles drawn will be red; 1.5%
How to calculate probability?
We are given;
Number of red marbles = 5
Number of blue marbles = 8
Number of Green marbles = 4
Total number of marbles = 5 + 8 + 4
Total number of marbles = 17
Probability of first being red = 5/17
Probability of second being red = 4/16
Probability of third being red = 3/15
Thus;
P(all three marbles drawn are red) = (5/17) * (4/16) * (3/15)
P(all three marbles drawn are red) = 0.0147
Approximating to nearest tenth of a percent = 0.015 = 1.5%

Work out the percentage change when a price of £80 is increased to £100
Answer:
25%
Step-by-step explanation:
100 - 80 = 20 (change)
change / original price X 100
20 / 80 = 0.25
0.25 X 100 = 25

what is g in this problem 4-(9g-5)=-18
Step-by-step explanation:
Let's solve your equation step-by-step.
4−(9g−5)=−18
Step 1: Simplify both sides of the equation.
4−(9g−5)=−18
4+−1(9g−5)=−18(Distribute the Negative Sign)
4+−1(9g)+(−1)(−5)=−18
4+−9g+5=−18
(−9g)+(4+5)=−18(Combine Like Terms)
−9g+9=−18
−9g+9=−18
Step 2: Subtract 9 from both sides.
−9g+9−9=−18−9
−9g=−27
Step 3: Divide both sides by -9.
−9g−9=−27−9
g=3

How is today's rhinoceros similar to the triceratops dinosaur of long ago? How is it different?
Answer:
Very, very distant relatives. Mammals and dinosaurs branched off from a common ancestor hundreds of millions of years ago. They may both have horns, but triceratops and rhinos are very different. Usually you wouldn't refer to them as “related.”
The graph shows a volume of ice cubes versus temperature in degrees celsius. Which of the statements is false?
A. The correlation coefficient is close to zero.
B. Temperature is strongly correlated to the volume of ice cubes.
C. Temperature is the explanatory variable.
D. The data show a negative linear relationship.
The statements which is false about the volume of ice cubes versus temperature graph is the correlation coefficient is close to zero.
What is the correlation coefficient?Correlation coefficient is used to calculate how strong the relationship is between the two variables.
When there is a statistical relationship between two or more variables, then they are said to be in correlation.
Types of correlation-
Positive correlation coefficient- When the value of correlation coefficient is positive, then the value of one variable increases with increase in other variable.Negative correlation coefficient- When the value of correlation coefficient is negative, then the value of one variable decreases with increase in other variable.
The graph shows a volume of ice cubes versus temperature in degrees Celsius.
For a perfect correlation, -1 or +1 values is ideal. Here, some relation can be seen in a negative straight line, which suggest that the correlation coefficient is not close to zero.
Both volume and temperature has strong correlation for linear line where, temperature is the explanatory variable.
Thus, the statements which is false about the volume of ice cubes versus temperature graph is the correlation coefficient is close to zero.
